System and method for identifying a component for a tire pressure monitoring system

ABSTRACT

A system and method for identifying a component, such as a sensor, for a Tire Pressure Monitoring System (TPMS) to be replaced for a vehicle of interest by performing a Quick Search or an Advanced Search of a TPMS Manager database. In the Quick Search, the user inputs year/make/model (Y/M/M) or Vehicle Identification Number (VIN). In the Advanced Search, the user inputs various physical attributes of the component to be replaced. All related superseded, alias or interchange parts with like communication or physical structure and relevant service components are determined and the results displayed to the user. A relearn procedure for the replacement TPMS component for the vehicle of interest identifies and validates scan tool compatibility. A report to the user of a cause/failure analysis of the component to be replaced can be displayed.

BACKGROUND OF THE INVENTION

Systems have been developed to monitor, for example, vehicle tire pressure, and to report the tire pressure to a receiver at a central monitoring station using radio transmissions. A typical remote automotive tire monitoring system includes a plurality of tire-based sensory transponders and a central, vehicle-based arrangement. The sensory transponders include a component that senses a tire condition, such as tire inflation pressure or tire temperature. Each transponder is capable of outputting a coded transmission that conveys sensed tire condition information and an identifier for reception by the vehicle-based arrangement. Within the vehicle-based arrangement, an electronic control unit (“ECU”) processes the conveyed information and controls provision of information regarding the sensed tire conditions to a vehicle operator. During operation of such a system, the vehicle operator is readily notified of a current tire condition, such as a low inflation pressure in a tire.

The Tire Industry Association (TIA) produces an annual Tire Pressure Monitoring System (TPMS) application and relearn guide. It provides an Original Equipment Manufacturer (OEM) part number, three aftermarket alias numbers and the relearn process in brief. What it does not provide are the vehicle exceptions, such as alloy wheels, steel wheels, high line system, low line system, or any parts supercessions within the OE number. While listing three aliases, it does not provide the other ten alias parts from other manufacturers. It does not match the service components to these items. It does not define the specific requirement in detail for system relearn. It does not match tool manufacturer, compatibility and process required to relearn the TPMS system. This limited listing of information only adds to the number of catalogs that produce partial information for the TPMS service cycle.

Simply, a GM dealer cannot service a TPMS of a Nissan due to lack of know how, parts and tooling. Many tire shops have avoided TPMS service due to the lack of information. If a company services a tire, they must service a TPMS. The growth of new technology only adds to the complexity and the population of parts.

SUMMARY OF THE INVENTION

The invention solves a huge problem that exists in the automotive industry related to TPMS by providing a system and method that simplifies a multi-catalog, multi-parts and multi-information source process to identify TPMS parts, parts aliases, parts suppressions, parts interchanges, parts service components, vehicle TPMS relearn processes and TPMS scan tool compatibility. This is achieved through a software “wizard” walk-through software program that incorporates images, text, videos and multiple filters that allow the user to complete the process with accuracy.

In one aspect of the invention, a method for identifying a component of a Tire Pressure Monitoring System (TPMS) to be replaced for a vehicle of interest comprises identifying an Original Equipment Manufacturer (OEM) component or an equivalent component for the vehicle of interest by inputting a group of subsets into a graphical user interface (GUI) of a Tire Pressure Monitoring System (TPMS) Manager software program.

DETAILED DESCRIPTION OF THE INVENTION

Referring now to FIGS. 1 and 2, basic flowcharts of the system and method is shown according to an embodiment of the invention. In general, the system and method of the invention determines a proper environment for a TPMS sensor for a vehicle of interest, i.e., determining whether a particular sensor is compatible with the actual sensor taken from the vehicle. If not, then the invention allows a user to program a generic sensor with a programming tool. The invention also enables the user to re-program the vehicle in a relearn process so that the vehicle is safe to drive with the replacement TPMS sensor. In addition, the invention provides a sensor track feature that tracks the reason(s) why the sensor taken from the vehicle of interest has failed, thereby providing valuable fault diagnostics tool for the tire industry (FIG. 17).

The system and method identifies TPMS parts, parts aliases, parts suppressions, parts interchanges, parts service components, vehicle TPMS relearn processes and TPMS scan tool compatibility. This is achieved through a TPMS software program “wizard” walk-through that incorporates images, text, videos and multiple filters that allow the user to complete the process with accuracy by accessing a TPMS Manager database, which is the driver behind the value and usefulness of the information presented to a user through a graphical user interface (GUI). The content population of the TPMS Manager database comprises data tables that include the following general categories: 1) Vendors; 2) Vehicles; 3) Service tools; 4) original equipment (OE) Sensors; 5) Interchanges and Aftermarket Sensors; 6) Service Kits; and 7) Service Kit Components. The database population details are given in the Appendix attached hereto.

Search for OEM Part

There are basically two types of searches for an original equipment manufacturer (OEM) part that can be performed by the user: 1) a Quick Search, and 2) an Advanced Search.

Quick Search

As shown in FIGS. 2 and 3, a user can perform a Quick Search of the TPMS Manager database by entering a group of subsets into the GUI of the TPMS software program. For Quick Search, these subsets includes the Year, Make and Model (Y/M/M) for the vehicle of interest. In addition, a group of subsets may need to be input by the user to further determine the exact Original Equipment Manufacturer (OEM) part. These subsets may include, for example, Sub Model, Couple, Sedan, Trim Level (i.e., LX Model), Alloy or Steel wheels, wheel size, MHz, Vehicle system type (High Line/Low Line, valve angle (i.e., 20 degrees or 40 degrees), or other determinants assigned to that vehicle and TPMS sensor.

If the user does not have the vehicle Y/M/M, the same results may be provided based on the input of the Vehicle Identification Number (VIN). This result may, however, require further input to subsets not determined in the VIN, like wheel material or system type.

The TPMS Manager software will execute algorithms for the type of input (Y/M/M or VIN) by the user to determine the following:

1) What are the vehicle requirements for service?

2) Is the scan tool compatible with the vehicle?

3) What is the relearn procedure of the vehicle?

4) Are there any alerts available for this vehicle?

Referring now to FIG. 4, the TPMS Manager stores results from the executed algorithms in a lookup table within the TPMS Manager software program, which is available for users to retrieve at any point in time. The left side of FIG. 4 shows options that can be selected by the user, such as vehicle relearn, service requirements and scan tool compatibility check. The right side of FIG. 4 shows a display of results, such as OEM component(s), supersession component, interchange component, and alias component (alternative part).

By clicking on any of the “Relearn”, “Replace” or “Service Kits” buttons, the “1K0-907-253D,” for example, would be selected as the current sensor of the vehicle of interest. Clicking on each button yields a different screen of stored results for the vehicle of interest. For example, clicking on the “Relearn” button displays a screen of the stored results shown in FIG. 5. Clicking on the “Replace” button displays a screen of stored results shown in FIG.

6. Clicking on the “Service Kits” button displays a screen of stored results shown in FIG. 7.

Advanced Search

The second type of search that can be performed by the user is an Advanced Search. The user selects the Advanced Search option by entering input in the Advanced Search section of FIGS. 2 and 3.

Here, a user enters any number of subsets into the Advanced Search of the TPMS Manager software program. A full list of each subset is shown in FIG. 8, but at the high level, a user may use one or many combinations of subsets to identify an OEM component. The TPMS Manager software program performs a dominance filtering technique based on “AND” matching. Thus, “Blue” and “Metal” selections would show only “BLUE” and “METAL” sensors. There is no way for a user to use “OR” logic within the query. The Advanced Search option will resolve at the results screen shown in FIG. 9. From this point, the user can navigate the results to select the desired sensor or service kit of interest. The user can also view attributes, images, and any other available data. The final step of Advanced Search is two paths: 1) the user can either save the results, or 2) navigate through selection to begin a new Quick Search. The TPMS Manager software program maintains any selections made in Advanced Search, and the data is carried forward into Quick Search.

Determining a Part

A user may need to determine the application, service requirements or communication of a TPMS sensor without having vehicle information. This may result when a sensor is not functioning and the user has no knowledge of its application, and whether it is a correct part or not. To determine a part in a reverse lookup system, the user enters information through a series of dominance filters.

A search by color of the sensor, the Federal Communications Commission (FCC) ID number, the Industry Canada (IC) number, the OEM part number on the part (if available), the valve design, whether it is one piece, two piece, rubber or aluminum or a combination of the above-mentioned filters will provide a result that can be traced back to the application, as shown in FIG. 10. This will allow a user located at TPMS service facility, for example, to accurately determine that the TPMS sensor is for a Hyundai vehicle, for example, as opposed to a Honda vehicle. Additionally, many TPMS sensors do not have an OEM part number on them, yet all are required to be labeled with the FCC and IC numbers. As the number of TPMS manufacturers increases in the aftermarket, it is easy to understand the need for parts identification.

Service Requirements of the Selected Part

It is recommended that a service facility replace some mechanical part of a TPMS sensor when a tire is dismounted for either tire replacement or repair. These TPMS components consist of critical air sealing parts that are unique to each sensor. Matching the correct service part is important for safety reasons because this is the barrier between a highly pressurized tire and sudden air loss. These components consists of an external cap, a valve core, a retaining nut, and a rubberized washer, O-ring or grommet. In some cases, the service kit may or many not include an aluminum valve stem. Once the sensor has been identified, the user can correctly match the service components. Again, the user is allowed to filter and drill down the information to a vendor specific part for that application using the dominance filtering technique of the TPMS Manager software program. These service parts are fragile and contribute to air loss through decomposition of the rubber and/or galvanic corrosion of the parts due to incompatibility of the metals. The user will find clearly and identifiable images and description of the corresponding service parts, as shown in FIG. 11.

Superseding Parts

By entering the Y/M/M, VIN, FCC, IC or filtered description, a user is given a resultant OEM part number. It is very common in the life cycle of an OEM art that future generations of like parts have part number that supersede to a new number. For example, Nissan/Infiniti P/N 40700-JKOOA was the factory or “birth” number of a TPMS sensor for a 2008 G35. This part number has superseded to 40700-JKOOB, then 40700-JKOOC. A typical service facility would not easily understand a vehicle that was equipped with sensors that hat three unique part numbers, yet were identical, except for the P/N. The inventions shows all superseded number in a “chain” related to the birth number. The user will find clearly identifiable images to support and understand the sequence of superseding parts, as shown in FIG. 12.

Alias Parts and Interchange Parts

By entering the Y/M/M, VIN, FCC, IC or filtered description, a user is given a resultant OEM part number. It is very common that manufacturers other than the OEM have produced replacement parts for a given application. The invention will provide a directory of Alias or Interchange parts that can be used in place of the OEM part. All alias and interchange parts will be supported by images and detailed descriptions, as shown in FIGS. 13 and 14. An alias part may have a distinctly different design or shape which in turn will require a different service component. The invention ties together all components based on results and selections made by the user. In other words, the invention confirms for the user the answer to the question; “will this part work on this vehicle?.”

Vehicle Relearn Procedure

By entering the Y/M/M, VIN or using a reverse lookup to determine the vehicle result, the user will then be shown a RELEARN procedure for the vehicle of interest, as shown in FIG. 5. Every vehicle equipped with a direct measuring TPMS system has a proprietary sequence of events or instructions that must be followed or undertaken to enable the sensor to communicate with the vehicle. Vehicle manufacturers devised their own unique sequence resulting in multiple relearn procedures and multiple exceptions and derivatives of relearn. A relearn is a set of instructions that must be followed. In many cases a scanning and diagnostic tool specified for TPMS must be used. These tools can trigger Low Frequency (LF) signals, collect transmission data and protocols, and embed collected data into the vehicle via and OBD port. In some relearns, a part of the vehicle acts as the initiator. Examples such as the headlamp switch, the key fob, the ignition cycle, the brake pedal, the Drivers Information Center (DIC) and countless other combinations. In some cases, a powerful magnet is required to activate a sensor for relearning. Other systems require some or all of the above AND driving the vehicle a prescribed distance and speed. Lastly, some systems learn automatically without instructions or sequences. These are called “auto-learn” systems. Understanding these instructions and sequences is critical to safely and successfully relearning the TPMS system. The user will find an abbreviated version, as well as a full text version, of each vehicles specific relearn procedure based on vehicle results.

Scan Tool Compatibility

By entering the Y/M/M, the user is shown results related to a scan tools compatibility to perform the relearn where a scan tool is required. A scan tool is required for relearn on a significant percentage of TPMS equipped vehicles. Scan tools vary in complexity size and functionality. A GM dealership will have a proprietary scan tool for just GM vehicles. The same applies to every other car maker out of necessity to service their own brands. In the aftermarket, there are many scan tool manufacturers who have tools that can cover many of the OEM platforms. However as new vehicles and TPMS systems are introduced the aftermarket manufacturers are lagging in adding these applications to their respective scan tool products. It is common that tool manufacturers update their tools, usually via a web browser, every week or month as applications are added. Knowing whether a scan tool currently be used by the user has the capability to perform the scan tool required relearn is a final critical aspect the TPMS service cycle. A service shop that proceeds to repair, install or service a TPMS sensor or system, only to ultimately find out that their scan tool is incapable of performing this final step, will most likely bear the responsibility of paying someone else, perhaps a competitor to perform this relearn. The invention allows a user to check the tool functionality BEFORE performing the work to ensure that a complete cycle of service can be performed, as shown in FIGS. 15 and 16. The results shows the user this result in a yes or no answer. An accompanying video of the relearn using the tool will support the yes result.

User Defined Administrative Setup

The TPMS Manager Software program allows the user to setup administrative information in the TPMS Manager software program as follows:

1. User Name and Configuration

2. TPMS service center locations

3. Preferred Vendor TPMS Scan Tools

4. Preferred Sensor Vendor

5. Preferred Sensor Kit Manufacturers

6. Sensor Track Report: Sales, Replacement, Vehicle Coverage Report

7. Support

Results from the Y/M/M driver will populate with only those vendors selected. When a product or selected company has or shows no inventory or no application the user may opt to “show all” within a group.

The architecture of the invention supports an integrated version to tie in with a companies existing inventory and management system. A web-based version supports other or non in house infrastructure methods of use.
